Solution Overview

Problem

Existing mouth and nose masks lack effective attachment methods that prevent slipping, shifting, and falling, while also failing to provide a secure seal against viral transmission and fogging of glasses, especially in dynamic environments.

Innovation Solution

Incorporating an adhesive tape with a removable tape that can be folded or split into two parts to attach securely to the mask, allowing for reorientation to expose the adhesive side for a tighter fit and improved sealing, eliminating the need for ear loops and wire brackets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive tape is attached to the face mask edge, then the attachment security is improved, but the mask may cause skin irritation or discomfort

Engineering Contradiction:
Improveattachment securityVSAvoidskin irritation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A release liner is introduced as an intermediary layer between the adhesive tape and the skin. The release liner can be partially removed to expose adhesive portions that contact the skin, providing a secure attachment while the liner material itself acts as a protective barrier against direct adhesive contact with the skin, thereby reducing irritation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The release liner is designed with different properties in different regions: adhesive portions are exposed at specific locations where attachment is needed, while other portions remain covered to provide skin protection. This local differentiation allows secure bonding where required while minimizing harmful contact with the skin.

Inventive Principle:
Principle #3Local quality

2Duration of action of stationary object

If the adhesive tape is made reusable with release liner, then the durability is improved, but the complexity of the device increases

Engineering Contradiction:
ImprovereusabilityVSAvoidstructure complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The release liner and adhesive tape are merged into a single integrated component assembly. The release liner is attached to the adhesive tape in a predetermined pattern, creating one unified reusable unit that simplifies application and removal while enabling multiple uses without significant adhesive degradation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adhesive tape is divided into multiple adhesive portions separated by non-adhesive regions on the release liner. This segmentation allows selective adhesion at different locations while maintaining the integrity of the entire reusable assembly, enabling flexible attachment and easy removal without compromising durability.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the adhesive tape sections are peeled off and reoriented, then the sealing effectiveness is improved, but the operation time increases

Engineering Contradiction:
Improvesealing effectivenessVSAvoidapplication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The adhesive tape is pre-configured on the release liner with predetermined adhesive portions positioned to correspond with the mask edges. This preliminary arrangement allows for rapid application by simply peeling and positioning the pre-oriented adhesive sections, minimizing the time required to achieve effective sealing without complex manipulation.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention aims to improve the fastening of a mouth and nose mask to the face of a wearer by using an adhesive tape, which has an adhesive side and an opposite non-adhesive side, with a release tape at least partially attached to the adhesive side, in connection with a mouth and nose mask, wherein the release tape is provided to be fastened to the mouth and nose mask, wherein, in the properly fastened state, (i) the release tape is folded over in the longitudinal direction and in cross-section is fastened substantially in a U-shape around at least part of at least one edge of the mouth and nose mask, or (ii) the release tape is in two parts and has an inner and an outer part, which are fastened to an inner side and outer side, respectively, of the mouth and nose mask (30) in each case along at least part of at least one edge of the mouth and nose mask (30) such that, in a first properly worn state, a portion of the adhesive tape with the non-adhesive side rests on the face of a person wearing the mouth and nose mask, and in a second properly worn state, by removing the portion from the release tape, the mouth and nose mask can be adhered to the face of the person by means of the portion with the adhesive side of the adhesive tape. The present invention also relates to a mouth and nose mask.
